Background/aims: The postoperative morbidity following pancreaticoduodenectomy (PD) remains very high. Somatostatin or octreotide are indicated in the prevention of pancreatic stump-related complications. The aim of this study is to compare the efficacy of somatostatin and octreotide after PD.
Methodology: Between November 2000 and December 2003 we collected prospectively clinical and biological data from patients with a benign or malignant pancreatic tumor requiring a PD. Fifty patients were randomized into two groups, 25 treated with somatostatin (group S) and 25 with octreotide (group O).
Results: There was no postoperative death. Complications occurred in 20 patients (40%), 11 in group S, 9 in group O (NS). General complications occurred in 7 patients in group S, and 5 patients in group O. Local complications related to the pancreatic stump were found in 4 patients in both groups. At the end of the period of administration of the two study drugs, 2 patients (8%) had a pancreatic fistula in group S and 3 in group O (12%) (p=0.52). A trend of more rapid decreased level of amylase and lipase concentrations in surgical drainage was observed in group S but it is not statistically significant (p=0.29).
Conclusions: In patients requiring PD for pancreatic tumor, somatostatin and octreotide seem to behave similarly in the postoperative period.

Background: Somatostatin analogs (SSAs) binding to and activating somatostatin receptors (SSTRs) have been extensively used for the treatment of neuroendocrine tumors (NETs). The currently approved synthetic SSAs have high affinity for SSTR2 (octreotide/lanreotide), or for SSTR2 and SSTR5 (pasireotide). These agents have shown symptoms control and antiproliferative effects in subsets of NET patients and this was associated to the expression of the targeted SSTRs.

Gallium-68-DOTA-D-phe1-try3-octreotide (Ga-DOTATOC) positron emission tomography/computed tomography (PET/CT) is a crucial diagnostic tool for neuroendocrine tumors (NET). Its accuracy is influenced by radiochemical purity and patient preparation. We present two cases where unexpected radiotracer uptake in Ga-DOTATOC PET/CT imaging was observed.

Background: Neuroendocrine tumors (NETs) are clinically diverse types of tumors that can arise anywhere in the body. Previous studies have shown that somatostatin receptors (SSTRs) are overexpressed on NET cell membranes relative to healthy tissue, allowing for tumor targeting through radiolabeled somatostatin analogs (SSAs). This work aims to develop a novel Zr-labeled tracer incorporating the SSA, octreotide (TOC), for positron emission tomography (PET) imaging of SSTR + NETs and predictive dosimetry calculations, leveraging the excellent nuclear (t = 3.

Ga-DOTATOC PET/CT is a functional imaging modality that has revolutionized the evaluation of well-differentiated neuroendocrine tumors (NETs) by targeting somatostatin receptors. This technique has largely replaced conventional gamma camera imaging with 111In-labeled octreotide due to its superior sensitivity and resolution. While the physiologic distribution, normal variations, and common pitfalls associated with Ga-DOTATOC imaging are well documented, rare but clinically significant pitfalls can still occur.

Insulinomas are rare pancreatic neuroendocrine tumors (NETs) characterized by autonomous insulin secretion leading to hypoglycemia. Malignant insulinomas are defined by the presence of metastases and present significant therapeutic challenges due to limited treatment options. We report the case of a 69-year-old woman with a two-month history of neuroglycopenic symptoms, including morning headaches, blurred vision, palpitations, and sweating, which were alleviated by sugar intake.
